IMPROVEMENT IN CHUR-Ns.

Specification forming port ofLetters Patent No;` 36,8l'l, dated October2d, 1862.

Z'o all whom .it may concern:

Be it known thatI I, .Limes `'1HoM1 so1-r,=of Vevey, Switzerland county,Indiana, have invented a new and nset'nl- Improvement i`n Ghurns; Vand Ido hereby declare the following i of a'crotch fastened to the coneavit'yof the tub` andflaring upward` to` facilitate the insertion of, thedash. A driveshnft, E, passing through: the side of the tub, enters thelower part o'f` the `crotch B.` The inner end `of the drive.

Y shaft1E-hasa notch or slit; e,`which, receiving the tongue cprojecting from `journal C,"en` ables the rotation of the dash;

The dash D' isa solid cylinder of wood,` armed on its' periphery`v` withlongitudinal ridges whose sidesd in one"directiou are'in. the plane ofth'easis, or nearly so. ProjectingV fronrthe periphery of the dash, inthe plane of the tongue c, isa handle, F, whichenables the withdrawaland insertion of i the dash. i

The support and centeringof the dash de-` pend wholly on `thehearingsBB', and its ro tation wholly on'the shaft E; t Operation:` The'shaft-E, being with its slit revertical, lthe dash D is lifted by`means-oi 'the bandi/elif, and is dropped into the erotches` milk beingintroduced the dash is' rotated in 4direction of ,'arrow. The rotationof the dash acts ntti-violently agitato the milk, both bythe -direet'`blow of the radial faces d and by cans `ingthe1iquid to strike thebottom ,and the sides ofthe tub, andals'o by a portion of theliquorbei-ng cariedaround with the dash and precipitated in the form ofspray into that be- Alovir. ,Thechurning having. been effected, the`butter is'gathered by a slow reyerse'rotatiou of the dash. The dashbeing now rotated to the proper position is easily withdrawn biy'niennsof the handle F. I j" l The plain and simple form andreadydel'tachability of the tub and dash .facilitate the separation ofbutter and cleansing of the parts.

i claim hereinasnew and'of my invention--r The arrangement of tub A,having the Haring crotches B B', in combination with the rotarydash D,having in one plane ahjandle, F, land the tongue c,`which tongnefisadapted to l couple with the notched shaft E, tlie'whole beingconstructed and operating in the manner setforth. .g t

Injtestimony of which invention I. hereunto set my hand. y v y .i JAMESTHOMPSON.
